DuctSox has added the SkeleCore Pull-Tight to its line of fabric duct products. The SkeleCore Pull-Tight is a fabric Retention and suspension system that uses a combination of internal hoops and tensioning baskets in order to maintain the shape and retention of fabric duct.
General Tools has introduced the new Mini-Anemometer/Psychrometer. The DAF3009 can measure all parameters associated with installing, testing, and fine-tuning the performance of an HVACR system. This includes airflow volume, airspeed, enthalpy, ambient temperature, dew point temperature, wet bulb temperature, wind chill index, and relative humidity.
MacroAir has released its new industrial fan line called AirVolution-D. According to the company, because of direct-drive motor technology, AirVolution-D is lighter, sleeker, and smarter without sacrificing power or efficiency. By completely eliminating the gearbox that can be found on traditional high-Volume, low speed (HVLS) fans currently on the market, more than 137 moving parts have been eliminated.
NexRev Inc., announced the availability of the DrivePak™ Advanced Rooftop Control (ARC). The control is an expanded model of the company’s DrivePak HVAC retrofit upgrade, which the company says incorporates advanced controls allowing customers to further capitalize the savings from DrivePak as well as additional prescriptive energy rebates and incentives.
Pottorff is has introduced its new EXA-645 combination louver. The company says it is a high-performance louver with Best-In-Class AMCA certified performance for free area (50.4%) and a pressure loss of 0.15 in. wg. @1,272 fpm (6.46 m/s). The EXA-645 features stationary drainable louver blades that protect against water penetration along with an integral airfoil blade control damper which will allow for positive shutoff protection from air intake and exhaust openings.
AMETEK Rotron has released a 19-in rack mountable liquid cooling heat exchanger assembly. The unit is one of a variety of similar heat exchangers that are designed to dissipate over 10kw of heat in demanding operating environments. The heat exchanger assembly is enclosed within a ruggedized 6U (10.5-in) aluminum chassis.

Groschopp, Inc. introduced a Brushless DC Motor and Control package. Groschopp’s family of brushless DC motors and gearmotors have been tested for pairings with the brushless DC control product line giving engineers a brushless DC motor and control package designed for optimal operation.
Greenheck’s new Energy Recovery Filter System incorporates energy recovery technology into kitchen exhaust hoods. The system captures the waste heat produced by the cooking appliances that would otherwise be exhausted from a kitchen hood and uses it to preheat a portion of the incoming water supply that is directed into the patented energy recovery filters.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
